| 摘 要： | ~(210)Pb的衰变半周期较短(25年),因而在近年来广泛用于现代沉积物的年龄测定。但是迄今对~(210)Pb的迁移性尚有不同认识。本文试图综合评述显示~(210)Pb在低温环境中迁移性的各种证据,并阐述控制~(210)Pb迁移性的各种条件,以便作为评估用~(210)Pb测定年龄方法精度的参考。

| Abstract: | With a short half decay (25 years), 210Pb is widely used in the dating of modern sediments. But there exists controversy on the migration and nonmigration of 210Pb. In a hope to improve evaluation of the precision of the 210Pb dating method, the authors present a review of the evidence of 210Pb migration in low temperature environment, and the controlling factors over such migration. |
